I have seen quite a few posts regarding the Factory Alarm Keyless Entry System. Hopefully this will answer a majority of your questions without having to start another thread.....

How do I program a remote?
Depending on the year of your vehicle, programming the remote is pretty simple:

For 2001-2006 Models: (the oblong remote with either 2 grey buttons or a blue and orange button)EDIT: Replacement remotes are the newer teardrop shape, but are programmed the same way. The 'trunk' button is another way to put the alarm in and out of valet mode.

**Make sure all windows, doors, hood and trunk are closed.
**Get in and close the door.
**Turn the key in the ignition to the 'ON" position 10 times within 15 seconds
**You should hear the horn/chirp
**Open and close the drivers side door.
**Press one button on the remote
**Open and close the drives side door
**If you have other remotes, repeat the last 2 steps for all remotes
**Remove key from the ignition
**The horn should beep/chirp again
**Check remote(s)

NOTE: If you mess up during any of the steps, remove the key from the ignition, open and close the drivers side door and start over.

NOTE: You must program all remotes at the same time. Remotes not programmed at the same time will no longer work.

PROBLEMS:

1. I can't get the horn to beep/chirp after turning the key in the ignition:
**Make sure you are turning the key fast enough.
**Make sure the car is not in valet mode (If you have a working remote.--See below for info on valet mode)
**Disconnect the battery for approx. 1 min. This will reset the alarm back to factory settings. HOWEVER: It is possible the alarm will start going off. Turn the key in the ignition 3 times and the alarm will stop.

2. The remote did not program:
**Try programming again.
**Check/replace the remote battery
**Try another remote if you have one. If the others took the programming, the remote is defective/dead battery

This process is a little more difficult. You can either attempt the process below or take the vehicle to a dealer.

NOTE: You need the transmitters 'ID' code. This is either located on the bag the remote came in or inside the remote on the circuit board. It is an 8 digit number.

**Close all doors, trunk and windows.
**Sit in vehicle and close the door
**Perform the following steps within 45 seconds
**Open and close the drivers side door once
**Turn the key in the ignition 10 times within 15 seconds. You will hear a beep. If you do not hear a beep, start over.
**Open and close the drivers side door again within 15 seconds of the beep. You will hear a tone that lasts for 30 seconds.
**Before the tone stops, press the door lock switch (on the door) to the lock position the same number of times as the first digit of the code. (For example, if the 1st digit is a 2, press lock 2 times). Do not wait more than 5 seconds between pressing lock each time
**The tone will stop when you start pressing lock.
**After entering the number, push the door lock switch to unlock within 5 seconds.
**Perform the steps with pressing lock and unlock for each additional number, remembering to press unlock between each number. For example, for the number 1234, press lock 1 time, then unlock, lock 2 times, then unlock, lock 3 times, then unlock, lock 4 times, unlock....
**After the 8th digit, the tone will sound again for 30 seconds
** Before the tone stops, repeat the lock/unlock steps and enter the code again
**When finished entering the code the second time, a beep will be heard and the door locks will operate on their own, indicating the remote is programmed.
**If you need to program another remote, start with the open and close door step for each additional remote

NOTE: You only have to program new remotes. Old remotes will still work without reprogramming them again. They each have their own individual codes.

PROBLEMS:

1. I didn't hear the chirp/tone
**You waited too long between steps, you need to start over.

2. I heard all the beeps/tones, but the remote still does not work
**The remote is defective.

My exterior lights no longer flash when I lock/unlock with the remote:

The vehicle is in VALET MODE
**Make sure the alarm is disarmed.
**Open the drivers side door.
**Press and hold unlock on the remote until the security light on the dash stops flashing.

EDIT: If you used to have an older style remote for MY 02-06, the trunk release button on the replacement (teardrop) remote can also be used to put the alarm in and out of valet mode.

NOTE: To put back in VALET MODE, repeat the above steps.

The security light on my dash is flashing:

If the light is flashing blink, pause, blink, pause, etc:
**This means the security system is armed. This is normal when the system is armed.

If the light is flashing blink blink, pause, blink blink, pause, etc:
**The alarm is in VALET MODE, see above.

The horn no longer beeps/chirps when I lock/unlock the car:

**Make sure all the doors, windows, trunk and hood are closed.
**Disarm the alarm.
**Press and hold BOTH buttons on the remote until the horn/chirp sounds.

NOTE: To turn the beep/chirp back off, repeat the steps above.

My alarm goes off when I use the key to unlock the door:

**Once the door is open, turn the key in the ignition 3 times to stop the alarm.
**OR, put the alarm in Valet Mode, see above
**Use the remote!

I Just replaced/disconnected my battery and now my lights are blinking and there is a clicking noise that can be heard inside the vehicle:

You need to reset your alarm:

**If you have an older model vehicle, 2001 and under, and have a remote, press unlock on the remote
**If you have an older model vehicle, 2001 and under, there is a reset button for the alarm located on the drivers side, left side of steering colum, down near where the dash trim ends. (Your owners manual has a pretty good picture of where it is located and what it looks like) Press and hold button for a second or two until the alarm is reset.

The horm/chirp does not work when I press lock or unlock. There is no sound:
